stacey, I eat two a day, even of the substitute. I've used the Kashi bars, at least the ones that are close in calories and protein. Luna bars are reported to be the closest to the actual LAWL bars in nutrition, but I use zone bars or south beach bars or various other bars, as long as it is close (160-180 calories and at least 8 grams of protein, but more is better). After over two years, I felt I needed some variety. Although I have had times where I ate no bars (also known as the time I gained a fair amount of weight)
